WooCommerce gallery images

Hello!

I have problem with my WooCommerce gallery.

As I create new product, filling it up (adding information, details, images and in gallery some images) and I’d like to create same product in another language – choosing from Languages the “flag + product name in another language”, it doesn’t load gallery images from previous language and I have to add them manually again.

I have same theme, plugins etc (copy-paste) in another site and there everything works. What am I missing here?
